UPRIGHT PIANO.

SPECIFICATION forming part of Letters Patent No 446,595, dated February 17', 1891. Application filed May 23, 1890. Serial No. 352,888. (No model.)

T0 to whom it may concern:

Be it known that I, HENRY L. Gnnvwaori,- of the village of West Troy, county of Albany, and State of New York, have invented a new and useful Improvement in Upright- Pianos, of which the following is a specification.

My invention relates to an improved piano constructed in two parts for convenience in handling.

As upright pianos are constructed ordinarily their depth and width make it diflicult to handle them when passing up stairways, through doors, or in other kinds of transportation, and where this class of pianos has heretofore been divided to facilitate handling the action mechanism was not divided, but made in one piece, and the removal of the action mechanism and its subsequent attachment called for the services of askilledworkman.

To divide the parts of the piano so that the action mechanism of thelatter is also divided, and the construction of the action mechanism so that it can be divided and the parts of the piano connected by ordinary intelligence is the object of my improvement.

Accompanying this specification to form a part of it there are three plates of drawings containing five figuresillustratingan upright piano made according to my improvement, with the same designation of parts by letterreference used in all of them.

In these illustrations, Figure l is a perspective of an upright piano containing my invention with the action mechanism removed, with the iron frame, the wires, and sounding-board in position, and with the finish-board on the front of the key-bank removed. Fig. shows a piano made according to my improvement, illustrated as facing.

the view, with the two parts of thepiano disconnected for removal or handling. Fig. 3 shows a back view of an upright piano containing my invention, and Fig. at shows as detached a plate used beneath the two parts of the key-bank to connect them. Fig. 5 designates the finish-board or key-slip made with dowel-pins and adapted to connect with the front of the piano just below the keyboard, to overlap and cover theunion ot the two parts at the front.

The several parts of the piano thus illustrated are designated by letter-reference, and the function of the parts is described as follows:

The letters 1 and P designate two piano parts that are made to disconnect and eonuect, so as to form one instrument.

The letters S S designate the sides; \V V, the wrest-board or top, divided in two parts at 20 B, the sounding-board, divided vertically in two parts Z2 51*; I, the iron frame, divided vertically in the two parts i t'; K, the key-bank, divided centrally and horizontally in the two parts R 7.1; and A the bridge divided vertically into the parts a a.

The letter F designates the action-frame, made in two parts and each having thebrackets f f, each of which connects at a with the iron frame parts 17 at theupper ends of the brackets and to the back cleat O, and at the bottom to the block N. These brackets in each half of the piano are adapted to receive the action mechanism, consisting of the trackers T, han'nner-rail R, and hammers ll.

The back 5 the piano consists of frame parts D D, each made with the interiorstiuls d, the central cross-brace (P, the sides (1", and the connecting-stiuls d, with the latter, where adjoining in vertical contact, adapted So to connect by means of bolts Zr, provided with heads h and nuts '22. i

The letter 31 designates a plate arranged to attach at the under side of the key-bank support to one ofthe piano parts, to lap under the other part, and to connect by means of screws or m to secure the parts in position.

The letters 1) designate the hitch-pins, t the tuning-pins, and W the wires.

The letterJdesignates a key-slip made with 93 dowel-pins p, and adapted to connect with the front of the piano below the key-board on the front part of the piano at E by means of dowel-holes made in the piano at c.

As thus made and arranged all the working 95 parts of the piano are retained inthcir action and tone, and by unscrewing the nuts n from the bolts Z), and then unscrewing one of the screws in the plate M, after having removed the key-slip J, the parts P Pot the piano may be separated to appear as shown at Fig. 2, in which condition it is easily handled. and conveyed through doors, up stairways, and into action mechanism, and the said divided parts rooms, where it would be impossible to take constructed and arranged to connect substanpianos where they are not thus divided. tially in the manner as and for the purposes Having thus described my invention, what set forth.
